-shingles to form a substantially integral roof having no seams through which the water may pass.

This invention consists in a shingle formed of a thin sheet metal cover, a thin sheet metal base and a filler of sound-deadening material; it also consists in a shingle of this type, the side edges of which are bent to form male and female members of joints for interlocking withadjacent shingles and for securing the base, the cover and the filler rigidly together.

It also comprises a shingle of thistype provided with an integral nailing strip; and it further comprises the novel details of construction shown and described, andparticularly pointed out in the claims.

I have discovered that very thin sheets of soft metal, particularly of copper, when hammered upon an asphalt surface, may be beaten into various forms without the metal becoming torn or broken in the slightest degree. This principle I have embodied in my improved shingle in which the blows of hail-stones or other objects upon a copper cover are resisted by an asphalt filler, the

result being that the copper is merely hammered or dented into the filler without becoming torn or broken in the slightest degree, as would be the case were the cover applied directly to the roof or other rigid support. Y

In the drawings, Figure 1 is a plan view of one embodiment of my invention. Fig. 2 is a section thereof on about the line22 of Fig. 1, showing the manner of interlocking with an adjacent shingle. Fig. 3 is a section on about the line 3 3 of Fig. Y1. Fig. 4 is a section on about the line 4 4 of Fig. 1, showing the manner in which an upper shingle overlaps a lower one. Fig. 5 is a section of the interlocking edges of two shingles of a modified construction.

Similar reference characters refer to like parts throughout the several views.

The sheet metal base, which may be of steel, is shown of substantially rectangular directly with the roof, and an embossed or struck out centra-l portion 2. One of the side edges of the base is bent upwardly at 3, then outwardly as indicated at 4, and is finally bent downwardly at 5 and returned .upon itself at 6 to form the female member of an interlocking connection between the shingle and an adjacent shingle. The opposite side edge of the base is bent upwardly g at 7, then inwardly at v8, and is then returned outwardly upon itself as indicated at 9, finally terminating in the corrugations 10 and flat nailing strip 11. The upper end of the base plate is ribbed or corrugated at 12 and may have a fiat edge 13 to engage with and receive the correspondingly ribbed or corrugated lower edge 14 and flat portion 15 of the shingle next above.

The cover portion shown in Figs. 2 and 3 comprises a relatively thin sheet of copper or lead 18 which is a counterpart in form of the sheet metal base with the single exception that the portion corresponding to the bend 3- is shorter than the latter, thereb forming between Ythe base plate and the cover plate a narrow space that may be lled ably dipped in liquid asphalt, after which the sheets and liller 19 are pressed tightly to,- gether. The asphalt, which is of a somewhat viscous nature, forms a bond between separation of the parts such as might be caused by blows 'or by expansion or contraction of the sheets in respect to each other. As shown in Figs. 2 and 3, the asphalt ller extends laterally only to the bends 3 and 7, respectively; it preferably extends to the upper and lower edges of the sheet (Fig. 4).

It is found desirable in some cases to extend the filling laterally throughout the sheet as indicated in Fig. 5. This construction is advantageous in that it deadens the vibration in the immediate vicinity of the joint and at the same time strengthens the latter, and also provides a better nailing strip. In this modication the female member is shown provided with the corrugation 21 corresponding tothe corrugation 10 in the nailing strip, thns more positively interlocking shape, having a flat portion 1 that contacts.

with asphalt 19. In the manufacture of the l shingle,-'the sheet Inetal base plate is preferthe two metal sheets which prevents any :hoeaaoa the parts than is the case wherein this corrugation is omitted.

A shingle constructed in accordance with my invention will be a non-conductor oi.2 heat or cold and when properly laid will torni an absolutely water tight covering tor the root which will not sweat or rust. ylhe metal covering oit the shingles will protect the latter from hail stones and heavy storms and io the body of the shingle inclosed by the covering will act to deaden the sound caused by heavy storms or hailstriliing the root.

ln 'the construction shown7 the cover pos sesses very little strength, but has great i5 wearing1 qualities. The steel base plate reinforces the cover and gives the shingle its strength, and the asphalt serves as a bond for preventing the cover from separating from the base platea besides deadening the 2o sound of rain or hail7 preventing any rusting ot the base plate, and affording a cushion into which the cover may sinh when subjected to blows. v

@wing to the tact that the coverings are constructed trom 'very thin metal the cost or a roo-lE covered with my improved shingles will be considerably less than the usual metal root.

lt will be understood that changes may be made in the details shown without departing 'from my invention. l/Vhile l prefer to term the cover oi3 copper or lead, it may be advisable in some cases tomale it olf aluminum or other metal. l do not, thereto-re, wish to be limited otherwise than as indicated by the subjoined claims.

l claim: l. A shingle comprising a thin cover sheet oit' metal whose strength is insufficient to to withstand the stresses to which the shingle is subjected, a relatively thicker sheet metal base plate and a thin filling of a sound-deadening material between the cover and base plate, the edges oi' the cover and the base plate being interlocked to hold the parts rigidly together.

2. l shingle comprising a thin cover sheet of metal'whose strength is insufficient to withstand the stresses to which the shingle is subjected, a relatively thicken sheet metal base plate spaced apart slightly Ytrom the cover, a thin lilling or" sound-deadening material between the cover and the base plate9 the cover and base plate being interloclred along one edge to :torni a female member and being interloclied along an opposite edge to form a male member whereby adjacent shingles may be secured together upon the root.

3. shingle ,comprising a thin copper cover sheetwhose strength is insuHicient to withstand the stresses to which the shingle is subjected, a sheet metal base plate spaced apart slightly there-trom, a thin lilling oit asphalt between the cover and base platea the whole being pressed tightly together whereby the asphalt serves as a bond between the cover and the base plate, the cover and base plate being interlocked along one edge to form a female member, and along the opposite edge to torni a male member whereby adjacent shingles may be secured together upon the roof.

ln testimony whereof l have signed this specilication in the presence ot two subscribing witnesses.
